Company with great knowledge of the sector, they clarified all my doubts, informing me of the most optimal system to improve the envelope of my home. Without a doubt very professional, today there are many companies but not all of them are prepared, nor do they have professional staff. Thank you always 😊

Jesús González

The first time I called them was in 2018 because the pool was very poorly used and the masons who came made me botched, so I decided to call this company and it was a 100% success. The pool today is like new. 2 months ago I called them again to get an estimate for humidity in the facade that gives shade all day and they have already solved the problem. Chapo!

Marcos Alfonso

Risks of not choosing the right company to apply thermal insulation

As occurs in other construction works, there are two very dangerous underlying elements for the client:

On the one hand, the lack of professionalism, frequently derived from companies created in 24 hours and that in Numerous occasions also disappear without warning. They are companies without real technical solvency, although with an attractive advertising package, which necessarily lead to malpractice: the use of low-quality materials in many cases, and what is more important, inappropriate in others. How is this possible? It is not difficult to find applications for combustible materials in false ceilings with incandescent lights, hygroscopic materials in air chambers with moisture derived from small leaks, even materials that promote the nesting of rodents and insects, and a long etcetera.

On the other hand, the high supply derived from the above, entails a war of low prices. The problem is that, to achieve such prices, they resort to qualitative and quantitative losses. And the fact is that, as it is definitely a type of insulation that is hidden in the air chamber, they succumb to the temptation of applying amounts well below what is necessary to achieve the desired result and of materials that are not always of the contracted quality.

What can I do: We recommend that you always use approved companies with certification as specialists in the field and that you demand guarantees, as well as your detailed final works certificate.
